Subject: lantiq: Add AR9 compatibility bits to DWC2 driver
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=404b183aa892cb00ea215068a41b56603b22a95a;p=openwrt%2Fstaging%2Fyousong.git

lantiq: Add AR9 compatibility bits to DWC2 driver

Add AR9 DTS definition to be recognized by the DWC2 driver.

The same driver parameters can be mostly used except that some boards
seem to erroneously report OTG HNP/SRP capability of the USB HCD.
Forcing the HNP/SRP off allows these boards to work with the DWC2 as well.
